Sulphuric acid plant. Here there are often opportunities to recover waste heat from the acid plant absorption towers and reuse it for heating in mineral processing steps. Examples where the heat can be reused are copper electrolyte heating, spent acid and zinc sulphate solution heating in zinc plants, boiler feed water heating, etc.

Jul 13, 2015 · A membrane wall design for sulfuric acid waste heat water tube boilers is suggested as the tube walls can be kept above the acid dew point. The feed water temperature entering the economizer has to be above 280 F to minimize low temperature corrosion concerns.The casing design has to handle the high gas pressure.

There are three basic types of sulphuric acid plants: Sulphur Burning Acid Regeneration Metallurgical. Acid regeneration plants include plants that decompose spent sulphuric acid into SO 2 and H 2O to be regenerated in to fresh acid and plants that take waste sulphur gases (H 2S, CS 2) to produce acid.
